To yieldably resistthe rotative movement of the invention will appear from the descriptionmember I6 seated in a radial bore I'I in the head to follow. Theinvention is defined and pointed member `to engage the threads of themember l. out in the claims. A C-shaped spring I8 is arranged Within theA structure which is a preferred embodiment housing I9 on the inner endof the head membr ing drawing, in which: this provides suitable frictionmeans so that rattle Fig. 1 is a side elevation of a structure embodyiseliminated even when there is a loose fit of the ing the features of myinvention, parts being brothreads and also the head is held so that itdoes although my improvements are Well adapted for the head which, inthe` embodiment illustrated, automobiles and `stationary engines and theconsists of the disk 25 secured on the end of the like. i control rodand engaging a recess 26 Within the The tubular support 2 is externallythreaded head, a retaining disk 2l being secured at the 50 at 3 toreceive the collar 4 engaging one side of end of the recess by upsettingas indicated at 28. the panel I and the nut 5 on the opposite side, Aclosure disk 29 is provided at the outer end a washer Ii being arrangedbetween the nut and of the grip I4. The grip is secured by means of thepanel or instrument board. Within this the radial set screw 30.

`5.5 tubular support is a tubular adjusting member 'I With the partsthus arranged, the object to 55 be controlled is adjusted toapproximately the position desired by pulling or pushing on the headpiece which moves the adjusting member bodily and also the control rod.For line adjustments of the control rod, the head piece is rotated andthrough its threaded engagementl with the adjusting member is movedthereby in or out and thereby adjusting the Acontrol rod relative to theadjusting member.

So far as applicant is aware, it has been common to attempt to adjustthrottles and the like solely by manual manipulation or thrusting thecontrol rod or pulling it out, fine adjustment being secured by a lighttapping on the head or hand piece of the control rod. Owing to the factthat considerable friction must be maintained to hold the parts'in theiradjusted position, it is extremely difficult to manipulate the controlrod for line adjustment by pushing and pulling.

I have by my improvements provided a means which may be very accuratelyadjusted and the parts remain in theirl adjusted positions. This is, asstated, highly desirable in multi-motored planes or wherever it isdesired to synchronize although it has advantages for use on singlemotors.

I have illustrated and described my improvements in an embodiment whichI consider very practical. I have not attempted to illustrate ordescribe other embodiments or adaptations as it is believed that thisrdisclosure wil-l enable those skilled in the art to embody .or adapt myimprovements as may be desired. f
